Abstract

THE CLASSICAL REVIEW at its best vividly. This probably was why A. E. Housman, as we are told in the preface, said that the translator had ' caught something of Homer'. The diction is simple, but, except for an unlucky phrase here and there, escapes the commonplace and the stilted. The metre, English hexameters, is treated with freedom, and some lines are hard to scan on any principle, accentual or quantitative, and the proper names especially suffer violence, e.g. ' At the home of my father, the mighty warrior, Alkinoos'. But most of the lines run easily and with no sacrifice of sense or order to metre-an unusual merit. The translation as a rule is free, but faithful in spirit, though here and there the tenses seem to have gone wrong and disturb the sense, as in the simile on p. 8. F. R. EARP.

Simultaneous excitation and ionisation of helium by fast projectiles

“…For simplicity we will just use the word 'shake' in this work. The strength of the interaction is described by the parameter K = 2qv0/ V introduced by Bohr (1948). The transition from the perturbative regime to a stronginteraction regime occurs around K = 1.…”

Comparison between quantal and classical scattering dynamics in singly charged ion - atom collisions

“…For such systems detailed comparisons between different theoretical approaches and experiments are at present not possible. Letter to the Editor When comparing CTMC and quantal differential cross sections it is important to construct a full quantal differential cross section, since the scattering event in ion-atom collisions in the keV energy range is not well defined in terms of pure repulsive or attractive potentials (Bohr 1948, Hansteen et al 1995. The differential cross section is constructed from SCCC results using the eikonal approximation (e.g.…”

Attosecond-scale dynamics in ion–atom collision versus laser–atom interaction

“…This is equivalent to considering the electron loss from the target during the scattering, the freed electron being captured or not. The phenomenon of charge transfer can then be viewed as the second stage of a two-step process, reminiscent of the approach first used by Bohr and Lindhardt to classically compute the capture events appearing in the ion-atom collision [26], and extended later within an impact parameter-dependent model [27]. The second point is that the curves calculated within the IC are closer to the collision case than the ones calculated within the TC.…”
